I changed my font for charlierubinstudio.com but when i click an image on the exhibit everything changes: (charlierubinstudio.com/collection/…)

That's because permalinks pages use the media.php template. You simply need to work the changes you made to the index.php template into your media.php template...

Also, I would add the typekit rules after the CSS block of rules - it's simply nicer than way. ;)
